Specification of Letters Patent.

Patented oet. 9, 190e.

- To @ZZ whom it may concern.

Be it known that I, WILLIAM H. WOOD- WARD, a citizen of the United States, residing at Waco, in the county of McLennan and State of Texas, have invented new and useful Improvements in Ealing-Presses, of which the following is a specification.

This invention relates. to -baling-presses, the object of the invention being to provide an effective apparatus of this character which operates to solidly compress material Without waste thereof and in afrapid manner.

A press including the invention can be advantageously employed for baling different kinds of material, such as hay, cotton, Sac.

In the drawings accompanying and'forming a part of this specification I illustrate a simple form of embodiment of the invention, which to enable those skilled in the art to practice said invention I will set forth in detail in the following description, while the novelty of the invention will be included in the claims succeeding said description.

In the drawings, Figure 1 is a side elevation of the improved baling-press. Fig. 2 is a top plan view of the same. Fig. 3 is a central longitudinal vertical section. Fig. 4 is a transverse section taken on the line 4 4 of Fig. 3. Fig. 5 is a detail view showing a modified form of feeder-carrier.

Like reference characters refer to like parts throughout the several views.

The press illustrated in the drawings includes a baling-chamber, as 2, in communication with a plunger-box, as 3, the material to be compressed being delivered through the upper open side of the plunger-box, where it is delivered by a reciprocating plunger, as 4, into the baling-chamber 2, the outer end and sides of the latter being open. The bales when made are ejected through the outer end of the baling-chamber 2.

The press may be mounted upon wheels, as

V5, whereby it can be readily transported from place to place. To the sides of the plungerbox 3 are fastened the beams 6, extending in parallelism outward from said box and connected at .intervals to form a frame for supporting a plunger-actuating member, as 7. The plunger-actuating member is shown as consisting of a gear of two similar sections,

between which is pivoted the outer end of a connecting-rod or pitman 8, the inner end of said rod being jointed to the plunger 4. It will be understood that when the gear-wheel 7 is rotated the plunger 4 will be reciprocated through the medium of the connecting-rod or pitman 8 in the plunger box or casing 3. The shaft ofthe gea -wheel 7 is supported by suitable bearings upon the beams 6.

Meshing with the sections of the two-part gear 7 are pinions, as 9, the shaft of which isv supported by suitable bearings upon the eams and carries a driving member, as 10, which is represented as consisting of a pulley or band-wheel. When the pulley or bandwheel is rotated, the plunger 4 through the intermediate mechanism will be moved back and forth in its box 3. Upon the sides and top of the plunger-box 3 are arranged outwardly-diverging plates, as 11, the sidesof the box being joined by a plate, as 12. The three plates present, in effect, a hopper into which the material to be baled is delivered, the plates serving to prevent scattering of such material.

Upon the forward movement of the plunwhich are inwardly bent to extend through slots or openings in the sides of the box. The fingers yield outwardly when material is forced into the baling-chamber by the advancing plunger. On the backward movement of the plunger the free ends of the iingers are projected inward into the plungerbox, so as to interpose stops across the plunger-box, which limit or prevent back motion of the material from the baling-chamber into the plunger-box. The side edges of the plunger are notched to receive the free portions of the lingers as the plunger completes its forward stroke.

Extending across the top of the plungerbox 8 is a rocking member, as 14, approximately cam shape in cross-section, the opposite ends of which are provided with journals vsupported for rocking motion by and extending through the side walls ofthe plunger-box. Fastened t0 the journals of the rocking member 14 are arms, as 15, to which are pivoted bars 16, headed at their lower ends, the bars extending between their ends through sin table guides, as 17, upon the sides of the box or casing 3. The bars are surrounded by coiledv IlO springs 18, which bear at their ends against the guides 17 and heads of the bars, so as to maintain the rocking member 14 normally in its operative position with its lower edge bej of the baling-chamber.

low the plane of the under surface of the top When, therefore, a mass of material is in the plunger-box 3 in front of the plunger and when the plunger is advanced, the mass of material will be moved forward with the upper sidethereof against the lower edge of the rocking member 14. On the continued forward movement of the plunger the said rocking member is moved in an upward direction by the pressure of the moving mass thereagainst, whereby the arms 15 will be elevated to put, through the intermediate parts, the coil-springs 18 under compression. As soon as the plunger moves backward the rocking member will be relieved of pressure, so that the springs 18 can return the said rocking member to its original position.

As the plunger moves'backward a feed device, as 19, becomes operative to double the material on itself, so that when the plunger again moves forward. the material will be compressed in doubled-up sections or loops. The feed device 19 is operative in unison wi th the plunger 4, it being shown as connected in the present case with a carrier, as 20, which receives its motion from the plunger. The carrieris represented as consisting of an anglelever pivoted between the ends of one of its branches between the posts or standards 21, which rise from the parallel beams 6. The feed device is suitably braced. To that branch of the angle-lever which is directly supported by the posts are connected links, as 22, jointed at their lower ends to the pivot of the joint 8, hereinafter more particularly.

described. I Would state that the joint 8a is between the plunger 4 and the pitman or connecting-rod 8. Upon the backward movement of the plunger the feed device 19 is projected downward into the plunger-box 3, so as to double the material on itself in advance of the plunger and to carry loose material into said box. As the plunger commences to move forward the feed device by reason of its connection with said plunger is lifted out of the path thereof, by reason of which the plun ger can freely advance, so as to press the material forward into the baling-chamber and to compact the material already in said balingchamber. The lfeed device therefore moves into and out of the plunger-box during the motion of lthe plunger, such action being automatic.

Connected to the upper side of the plunger in some fixed manner is a plate 24, extending from one side to the other of the plunger-box, and to the outer side of which is hinged a swinging plate, as 25, flexibly connected, as by a rope 26, with the plate 12. The two plates 24 and 25 protect the joint between the pitman 8 and the plunger 4 to prevent the entrance of foreign matter into the oint from above the same. When the plunger 4 is moved rearward, the under side of the swinging plate 25 will be engaged by an actuating projection, as 27, upon the pitman or rod 8, so as to swing said plate upward and prevent any material being drawn rearward with the plunger from the upper side of the plunger-box. When the pitman has moved a certain distance rearwardly, the projection 27 will pass free of the plate. Beyond this point the plate is further elevated by reason of its connection with a fixed part of the machine. As the plunger moves forward the plate drops by its own weight to its original position.

The pitman or connecting-rod 8 is shown as being loosely connected with the plunger 4, the connection being a free pivotal one and being denoted in a general way by 8a. Fastened to the upper and lower sides of the pitman adjacent the plunger are arms 8b of duplicate construction and adapted to coperate with avplate 8C, fastened to the inner side of the plunger. Just before the plunger reaches the extreme inner end of its stroke the free ends of the arms 8b will engage the plunger to cause it to complete the stroke and with a powerful pressure, the strain being taken off the pivotal connection between the pitman and the plunger. The arms 8b may, if desired, be resilient.

In Fig. 5 the feed device or feeder 19 is represented as connected with a resilient'carrier 20, the opposite end of the carrier being pivotally connected with the pitman 8.V lThe feed device or feeder 19 operates exactly like the feeder or feed device 19, hereinbefore described, for which reason I have given them corresponding characters. l .The carrier is represented as consisting of a bowed spring passing between its ends through a guide, as 20h, carried by the posts 22a.
